The ninja jack. The act of jacking off silently (quickly in most cases) and without those around you knowing that you had even done so.

Usually refers to jacking off while someone is talking on the phone (I.e. a girlfriend calls and you rub one out while she talks about something random).

Girl: "Hey, so anyways my day blah blah blah"
Guy: "yup, sounds good"
Guy::touching himself/finishes::
Girl: "So- what do you think?"
Guy: "Sounds like a plan. We meet at your parents house for dinner tomorrow night"

Ninja jack successful.

Girl: "What's wrong- you sound winded"

Ninja Balls 

Ninja Balls are the inhalable food invented by Ryan J. Reynolds in Episode 28 of WillyousignmyCast that you throw down onto the ground like an actual ninja ball, let the smoke/mist fill the room, and ingest the flavor of your favorite foods as opposed to actually spending large amounts of money on the foods themselves. For example: Hot dog, pizza, salad, pork bacon, shark and sharktopus.

WARNING: 40% alcohol content...

Ryan: Ninja Balls are the way of the future.
Brian: Ninja Balls are the way of the STUPID.
Ryan: That's like saying you can't do the printing press or the telegram because it's impossible. Ninja Ballin' like a mothaf*cka!
